Abstract:Improvement of external quantum efficiency of silicide Schottkybarrier detectors in the 3 to 5 μm waveband with subwavelength-grating incident plane," Opt. Eng.Abstract. Silicide Schottky-barrier midwave infrared detectors for the 3 to 5 μm waveband typically use a 2 to 8 nm metal-silicide layer grown on silicon substrates as an absorption layer. We demonstrate the use of an SiO 2 -film-coated subwavelength grating as an antireflection incident plane in such detectors to enhance absorption at the 3 to 5 μm wav… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
